Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

    I have been battling fleas for a little over a month. I bought this a few weeks ago, but kept insisting that I didn't need to use it yet. I topically treated my cats first. Well well well, a month later and of course, my cats still had fleas. So I used this. I have a one bedroom apartment, so I did it in two sections. I sprayed down my bedroom, every inch of molding around the floor, the base of my bed (not the mattress) and the rug. Opened the windows and locked us out for 3 hours (even though the bottle says 2 my cat has asthma so I was being very cautious). Then right before bed, we moved everything into our bedroom (cats, food, water, litter box, all my plants) and I sprayed the rest of my I have been battling fleas for a little over a month.

Couch, rugs, the trim around the floors, the cat trees, everything I could. I probably used more than recommended (one bottle worked for my 400-500 square ft apartment) but I did not want to treat again. Next day, put topical treatment on my cats. We found less than 5 fleas on them the next day. One week later, we have not found ONE FLEA. Amazing. My cat has been coughing more than usual (again, he does have asthma which is why I put this off in the first place) but it could also be due to the changing of seasons. Highly recommend so far. I am very happy with the results. I see no damage to my furniture, wood trim, or the laminate flooring. … more

    LOVE IT SO MUCH!!!

    We’ve been battling a flea infestation that came on so sudden about a month ago. We tried sprays and bathing them once a week, Terminix came out and sprayed and still nothing was slowing them down. I used this and within 24 hours there were barely any active fleas. I sprayed again this evening and I’m betting we won’t have any active by this time tomorrow. This was LITERALLY A GODSEND! We’ve been boarding our cat and dog and I called today to extend until we can 100% be sure they’re all gone before bringing them back home! We also sprayed our yard to cover all bases!

    It worked!

    By on

    I tried to get rid of these nasty fleas by using natural care, which works well with regular reapplication; however, went away for the weekend during a hot spell and came home to an explosion. Gave up on Natural Care, bought Advantage Carpet and Upholstery Spot Spray. So far I have sprayed my bedroom 2x with it, (last time was yesterday morning) and tonight I’ve pulled at least 40-50 fleas off my pants. Doesn’t work. After it didn’t work the first time I ordered Virbac. It came and I sprayed my hallway/stairs and 1 bedroom. I came home to no fleas in those areas. I have cats and a dog so can only do a section of house at a time to keep them from being exposed.

    This product works!!

    By on

    I had a really bad flea infestation in my house. I couldn’t walk anywhere without fleas hopping on me let alone them torturing my cat. I got my cat treated and bought this for my home. I waited 2 hours for us to return to the treated areas (did downstairs first then upstairs) and did vacuum once. I haven’t seen a flea since! I highly recommend and will keep a can on hand at all times.

    It works. What more do I need to say?

    By on

    Read and follow the directions. It works. I also in desperation sprayed it on the center of my carpet overnight, vacuuming the next day. It worked but only lasted until I vacuumed it up. This is not recommended and is expensive. It got rid of the fleas. I am ordering a new can and having my carpet and upholstered furniture hot water extracted, the closest I could find to steaming. I recommend this product.

    Definitely works, but buy more than one can

    By on

    This stuff is awesome. Some people complain that it’s expensive but if you’ve ever had a flea infestation then you know it’s worth shelling out some extra cash to get it taken care of quickly. This stuff definitely works but you have to make sure you use it according to the instructions, and be generous with how much you use! I sprayed this stuff everywhere in my house from top to bottom: between mattresses, in the cracks between my hardwood floor slats, the basement, even in my car because my dogs are frequent passengers. You need to use this anywhere and everywhere your pets go because that’s where the fleas will be. Hope this helps.

    Verbal did kill the adult fleas but 2 weeks later my house was infested again. The claim that it will last for months did not hold up.

    Not as effective as we had hoped

    By on

    This killed the initial round of fleas, but it has not kept killing them as stated. We have fleas again despite all pets being on preventative and regular vacuuming. This spray is too expensive to not work well!

    Buying It Again

    By on

    I purchased this four years ago when our cat was infested at the vet. I have tried all sorts of things over the last thirty years. This worked better than bombs and professional exterminators. I was so impressed that I'm purchasing it again since the local feral cat came down our chimney and infested our new kittens.
